Can't agree more. Now if only RealFlow were not that expensive and we had
some easy means to convert POV-Ray-scenes into something RealFlow could
use...

I prefer writing my own code or using an open source solution for this kind
of stuff....... *if* I find the time to put any effort into it!

The above quote is the crucial part: how often does one have time (and
skill) to write a fully fledged particle-based fluid-simulation which works
near-flawlessly? But doing things yourself is the most rewarding, I agree
with you there.

Absolutely. Just converting the ASCII text files that RealFlow outputs to a form that
my macro
reads can sometimes take all night. It's all a real pain, and is unusable for real
scenes.

So would I if (a) I were able to code it, or (b) there was one available.

Yes, I agree about the rewarding aspect, and you've said it before on more than one
occasion
that you like to code everything yourself in SDL. I would do that too, were I able.

Are you doing it by hand? I don't know what the RealFlow output looks
like, but usually Perl is a very powerful tool to solve such conversion
problems.
Cool animation, BTW. I'm not sure if I like it that the two fluids don't
really mix up, I guess my mind thinks that there should be some gradient
between the two fluids once they've touched. Is RealFlow able to do that?

No, I'm using TextPipe Pro. With tens of thousands of particles, it really slows down.

Thankyou. I think that, yes, RealFlow is able to mix the colours if I were to texture
them
*inside* RealFlow, but I'm really only outputting the positions of each particle, and
then
including them inside one of two 'blob' objects. I think that if I were to give each
particle
an individual pigment and placed the entire set of particles within just one blob, POV
should
merge the pigments together, but this is untested, and would use many times more RAM
too
(again... untested).
